There's a saying in Mexico "al buen entendedor pocas palabras" wich means to the good listener few words, this is a very good film, it shows a very good portrait of the reality in Mexico, the gap of social classes it's just like that, how people live in both worlds, how society treats the lower class like they're nothing, the impotence like their words don't matter at all. Definitely it's a movie that doesn't explain that much but it says it all, with great cinematography, good acting.
